Improper operation of a hoist can create a potentially hazardous situation which, if not avoided, could result in minor or moderate injury, or property damage. To avoid such a potentially hazardous situation THE OPERATOR SHALL:
•Maintain a firm footing or be otherwise secured when operating the hoist.
•Check brake function by tensioning the hoist prior to each lift operation.
•Use hook latches. Latches are to retain slings, chains, etc. under slack conditions only.
•Make sure the hook latches are closed and not supporting any parts of the load.
•Make sure the load is free to move and will clear all obstructions.
•Avoid swinging the load or hook.
•Make sure hook travel is in the same direction as shown on controls.
•Inspect the hoist regularly, replace damaged or
worn parts, and keep appropriate records of maintenance.
•Use the hoist manufacturer’s recommended parts when repairing the unit.
•Lubricate load chain per hoist manufacturer’s recommendations.
•NOT use the hoist load limiting or warning device to measure load.
•NOT allow your attention to be diverted from operating the hoist.
•NOT allow the hoist to be subjected to sharp contact with other hoists, structures, or objects through misuse.
•NOT adjust or repair the hoist unless qualified to perform such adjustments or repair.
1)Face the hand chain wheel side of the hoist.
2)To raise the load, pull hand chain clockwise.
3)To lower the load, pull hand chain counterclockwise.
NOTE: The clicking sound of the pawl when a load is being raised indicates normal operation.
4.4Principle and Operation of the Slip Clutch
: IMPROPER chain hoist use could result in death or serious injury. To avoid these hazards:
: NEVER disassemble or attempt to adjust the slip clutch assemby. Any attempt to do so will void the warranty. Contact your closest Harrington Distributor if service is required.
The standard slip clutch device prevents the hoist from being used to lift damaging loads beyond the rated capacity of the manual chain hoist. When an applied load exceeds the preset value, the hand chain wheel rotates idly. The mechanism is a friction clutch system located between the hand chain wheel and the mechanical brake.
